Default Any advantage of long gear vs short?

I'm trying to decide on gear leg length for my 4 build. I have a nos mount with short gear legs available.
My question is:
What advantages are gained with the long gear legs?
Thanks

Default Clearance

Prop clearance is the big one and it is especially true of you go with a constant speed and/or o-360. Level attitude my -4 with 360 and hartzel has about 6 or 7 inches when I pick the tail up off the ground.

Whichever you decide, try and get pre-drilled gear legs if available. Aligning and drilling the gear legs is a real PITA.

I cannot state this as fact; however, it was interesting to hear and worth some validation. A well known and respected TW instructor in Winter Haven FL claims that the short leg 4 is not (always?) in full stall at touchdown thus making it less safe to a degree vs other tail draggers. I’m sure this will be a bit controversial here but it made sense at the time. Not debating wheel versus three point landings. I’d always wondered what the community here would say and this thread seems a decent place to broach this topic.

Default Either is fine, but..

I've flown both and I built my 4 with longs because that was standard at the time. I would build long again and recommend for others. Your unused short set would probably sell to rebuilders or repairs quickly if you chose to order longs. The 4 lands 3 point slightly better with longs, but if I have a PAX, I can still hit the TW first . I believe resale is better with longs, but if I was shoping, I would not let short vs long be a deal breaker. They are all incredible machines.

+1
IMHO, there are many other dealbreakers way above gear length.
FWIW, I have a short gear -4. The flatter landing attitude means that it flys onto the deck with all 3 points. I find the lower AOA at touchdown is an advantage in gusty crosswinds.

None of the tailwheel RVs are at "full stall" in 3-point attitude!

Longer gear gives better prop clearance. Shorter gear gives better forward visibility while taxiing. Landing attitude doesn't make a huge difference. You learn to land whatever you have.

Well, my humble experience on the -8 says otherwise…

And my humble expedience in the -8 says otherwise to your humble experience.

My experience has been the -8 three point attitude is not a full stall at landing attitude.
